A fractional micro-macro model for crowds of pedestrians based on fractional mean field games

From a very young age, we’re warned against shouting “Fire!” in a crowded theater. The possibility of inciting mass panic presents an obvious moral problem. But for researchers, the situation also presents an interesting mathematical problem: How do large crowds of people behave in emergency situations? While many have turned to classical physics and calculus…

Should we sample time series more frequently?

A team of statisticians from the Universities of Bristol and Southampton and the Office for National Statistics have been chosen to present a prestigious Read (Discussion) Paper at a plenary session of the Royal Statistical Society’s international conference in Manchester today (Tuesday, September 6). The paper presents new research in the field of time series…

New electricity grids possible with computer simulations

Detail of a simulation of a pulsed positive discharge near a dielectric rod, made by Anna Dubinova. Credit: CWI Renewable energy requires new electricity grids, sometimes over entire continents, because ‘green energy’ is often generated in remote locations. A general problem in such networks is that, although electrically conductive parts are separated from their environment…

Researchers plumb the secrets of tissue paper

UBC mechanical engineering researchers Srikanth Phani, Kui Pan and Sheldon Green Credit: UBC Canada’s tissue manufacturers are now much closer to producing the perfect paper, thanks to new UBC research. A team working with UBC mechanical engineering professors Sheldon Green and Srikanth Phani have created what is likely the first complete mathematical model of creping,…
